Museu do Caramulo Listed by thegentlemen Ransomware Group: Ransomware Claim — What’s Alleged & What To Do

On February 10, 2026, the Museu do Caramulo appeared on a listing associated with the ransomware group thegentlemen. The entry states that internal files were exfiltrated during a ransomware attack on the Portuguese museum. No figure has been released for the number of individuals affected, and the museum has not issued a public statement confirming or detailing the incident. This development occurs against a backdrop of sustained ransomware activity targeting organisations that hold both operational records and public-facing data. Listings on leak sites serve as a pressure tactic, regardless of whether the underlying claims are later verified by the victim.

Breaking down the breach

The only confirmed information is the February 10, 2026 listing itself and the statement that internal files were taken. No timeline for the intrusion, no volume of data, and no description of the encryption or exfiltration methods have been disclosed. The number of people whose information may be involved is also unknown.

Inside thegentlemen

Thegentlemen is a ransomware operation that maintains a public leak site where it lists organisations it claims to have compromised. Such groups commonly encrypt systems and threaten to publish stolen material if a ransom demand is not met. The listing of Museu do Caramulo constitutes the group’s claim; independent confirmation of the data’s contents or the attack’s scope has not been provided.

About Museu do Caramulo

Museu do Caramulo maintains collections of art, historic vehicles and related cultural objects, and it organises public exhibitions and events. Organisations of this type routinely process visitor registrations, membership records, supplier contracts, insurance documentation and internal administrative files. A breach therefore touches both the institution’s operational continuity and the personal information of individuals who interact with it.

What data was at risk

The listing refers only to “internal files.” The precise categories of data contained in those files have not been published. Museums and similar cultural bodies typically hold contact details, payment records, event-participant information and staff records; however, whether any of these specific data types were present in the exfiltrated material remains unconfirmed.

The real-world impact

Individuals whose details appear in internal files could face increased risk of targeted phishing or account misuse if the material is later published or sold. For the museum, the incident may complicate insurance claims, regulatory reporting obligations and relationships with donors and partners. The absence of Reported Details limits any further assessment of scale or severity at this stage.
